JAMES M. LAIELIN, OF BOISE, IDAHO.

COMBINATION PLIERS AND WRENCH.

Application filed August 14, 1923.

To all whom it may concern:

Be it known that I, JAMES M. LAFLIN, residing at Boise, in the county ofAda and State of Idaho, whose post-office ad-v dress is 413 BroadStreet, Boise, Idaho, a native-born citizen of the 'United States, haveinvented certain new and useful Improvements in Combination Pliers andVrenches, of which the following is a specification.

My present invention relates to combination pliers and wrenches, andparticularly to a tool of the cross handle type.

An object of this invention is to provide a tool which can be used aspliers or a wrench, without adjustment or manipulation of the parts forthe interchangeable use.

A further object is to provide a tool of this character which is soconstructed that the jaws can be of tool steel or other suitablehardened and wear-resisting meta-l, while the handles and remainingportions can be of any other suitable metal which can be readily workedand shaped.

A still further object resides in so constructing and assembling theparts that the jaw portions can be readily removed and replaced, withoutthe use of special tools or equipment.

Another object is to provide a tool of this character in which the mainworking bearing is contained within the jaw struc- 'ture.

With these and other objects in view, which will be apparent from thediscription and drawings, my invention includes certain novel featuresof construction and combination of parts which will now be set forth andthen pointed out in the claims.

In the drawings:

Figure 1 is a plan view of a tool constructed in accordance with thisinvention.

Fig. 2 is a view in edge elevation.

Fig. 3 is a view similar to Fig. 1 taken from the opposite side.

Fig. 4 is a plan view of one of the handle members. I

Fig. 5 is an edge elevation of the member shown in Fig. 4.

Fig. 6 is a view similar to Fig. 4 showing the remaining handle member.

Fig. 7 is an edge elevation of the member shown in Fig. 6.

Serial No. 657,286.

Fig. 8 is a transverse sectional view on line 88 of Fig. 1.

Fig. 9 is a sectional view online 9-9 of Fig. '1.

Fig-10- is a plan view of the jaws.

V The handles 1 and 2 are curved, as at 3 and 4, so that the handleportions lie in substantially parallel relation and the ends 5 and 6,corresponding to the jaw portions of the usual pliers, are crossed, andare in opposed relation. The ends 5 and 6 are recessed as at 7 and 8,and are provided with the bearing ears 9 and 10, which ears are off-setto interfit when the handles are placed in crossed relation. The ends 5and 6 are provided with openings 11 and 12, extending substantiallyparallel with the openings of the bearing ears 9 and 10, and these endsare recessed as at 13 and 14 on adjacent sides.

The jaw members 15 and 16 are substantially semi-circular in outline tofit within the recesses 7 and 8 of the ends 5 and 6 of the handles, andthese jaw members are provided with interfitting bearing ears 17 and 18.A. pin 19 is riveted or otherwise secured in the openings of the bearingears to pivotally connect the jaw members 15 and 16, and this pin has anextending screwthreaded end 20 adapted to fit through the openings ofthe ears 9 and 10 of the handle members when the jaw members are fittedin the recesses 7 and 8, a nut 21 being turned onto the threaded end 20to hold the parts in assembled position. Pins 22 and 23 are connected inthe ends of the jaw members 15 and 16 and are provided with threadedextending ends 24, which fit through the openings 11 and 12 of thehandle members, nuts 25 and 26 being turned onto these threaded ends torigidly hold and secure the jaw members within the recesses 7 and 8 ofthe ends 5 and 6 of handle members I 1 and 2.

The adjacent faces of jaw members 15 and 16 are recessed as at 27 and 28to give an opening of polygonal form when the plier handles are opened,and the abuting faces 29 and 30 of these jaw members might be scored orotherwise roughened to give a better grip when the tool is used as agripping plier. Also, the faces 31 and 32 of the ends 5 and 6 may bescored or roughened. The recesses 13 and 14 of these ends 5 and 6 can beincreased in size and pairs of jaw members having wrench socket recessesor openings of different sizes and configurations can be fitted and usedin conjunction with the pliers handles.

While I have herein shown and described only certain specifiedembodiments and have set forth only certain possible modifications, itwill be appreciated that various changes and modifications can be madein the form, arrangement and manner of assembling the parts, withoutdeparting from the spirit and scope of my invention.

I claim:

1, A combination plier and wrench, comprising a pair of crossed handleshaving bearing ears spaced from the point of crossing and having theirends recessed adjacent said ears, a pair of jaws pivotally connectedtogether adapted :to be fitted within the recesses with their pivotmounting in line with the bearing ears, and means to hold the jaws inplace in the recesses.

2. A combination plier and wrench, comprising a pair of handle memberscurved to cross adjacent their ends and having said ends r cessed onadjacent faces, a pair of jaws adapted to fit within the recessespivotally connected together, and means to secure said jaws within therecesses and pivot said handles for swinging movement.

3. A combination plier and wrench comprising a pair or handle members,each curved adjacent one end to be fitted in crossed relation and'havingthe crossed ends recessed on acent faces, said recessed ends beingprovided with bearing ears and having openings at points spaced fromsaid ears, a pair of aw members provided with interfitting bearingportions, a pin pivota'l l-y connecting said j aW members having athreaded extension to fit through the hearingears of the handle memberswhen the jaws are fitted in the recesses, .a nut turned onto thethreaded :end to hold the handles in assembled relation, threaded pinscarried by said jaw members to fit through the openings of the recessedends and nuts turned onto said threaded pins to secure the jaw membersin place.

In testimony whereof I hereunto afiix my signature.

JAMES M. LAFLIN.
